Abstract

The invention discloses a high-power curved waveguide, which includes a curved waveguide body. Both sides of the curved waveguide body are symmetrically provided with a liquid-cooled heat-dissipating liquid inlet tank and a liquid-cooled heat-dissipating liquid outlet groove for cooling liquid. The output end of the slot is connected to the input end of the liquid cooling and heat dissipation liquid outlet slot; the curved waveguide body includes a light wall horn, a circular polarizer, a transition section, a curved waveguide, a coupler and a circular waveguide elbow, and the circular waveguide elbow The output end is connected to the input end of the coupler, the output end of the coupler is connected to the input end of the curved waveguide, the output end of the curved waveguide is connected to the transition section, the output end of the transition section is connected to the input end of the circular polarizer, The output end of the circular polarizer is connected with the input end of the light wall horn. The cooling liquid enters the liquid cooling and heat dissipation liquid inlet tank from the input end of the liquid cooling and heat dissipation liquid inlet tank, flows through the curved waveguide body, and then flows out through the liquid cooling and heat dissipation liquid outlet tank to realize heat dissipation for the curved waveguide, and the cooling liquid dissipates heat without It will bring new interference to the curved waveguide.

Description

technical field [0001] The invention belongs to the technical field of radar antennas, and in particular relates to a high-power waveguide feed source assembly. Background technique [0002] In the remote sensing satellite data receiving system, the feed source, as the primary radiator of the antenna, is the heart of the antenna and an indispensable component. Its performance directly affects the performance of the entire ground data receiving system. With the development of earth observation technology and remote sensing application requirements, the requirements for remote sensing satellite ground data receiving system are also getting higher and higher. Wider frequency band, higher frequency, dual-frequency or multi-frequency sharing technology has become a new technology development trend. . [0003] According to different antenna structures, feed sources are also divided into two categories: one is feed-forward feed, which is suitable for common feed-forward parabolic ...
